Toall whom it may concern: i v

Be'it known that I,VV1LL1AM"H.BIKE, J r., a citizen of the Unite'dStates, and ares'ident of the city of Orange, county of Essex, and State of New Jersey,- have invented certain new and useful Im rovementsin Recording Mechanism, of whic 1 the following is a speci fication.

My invention relates to that class of recording mechanism in which hammers or othe r devices actuated by pressure or percuss vely, are brought to act u on type supporte clby movable carriers EtTIL brought into position above a platen.

My invention consists of means whereby to control the action of the hammers, as, fully set forth hereinafter and as illustrated in the accompanying drawings, in whichv Figure 1 is a sectional elevation of sullicient of a recording mechanism" to illustrate my invention; and Fig. 2 is a front. elevation showing a sufficient number of parts to enablethe construction to be understood.

For purposes of illustration I have shown my improvements in connection with a ccylin'drical platen B, a series of type carriers each carrying a number of ty e T capable of slidin longitudinally, and iammers or pushers I pivoted on a shaft '1, which parts may be of suitable construction, and'which as shown corres ond to those of a similar construction an arrangement illustrated in my LettersPatent #763,692, issued June 28,'

1904. "Vith the type carriers 0 in all appaf ratus of this character are combined means for ,moving the said carriers so as to bring spring 2 being connected to an arm-3 of each 'difi'erent type into position to print, said moving means in the construction shown hein provided with strips S pivoted to the tars of the carriers and serving by their longitudinal movements of different extents.

to set'thc carriers in positions to bring differ ent type above the platen. The hammers H ma 1 be reciprocated or vibrated in any suitable manner. As shown, theyare springactuated, so as to operate percussiyely, a

"hammer, and the hammers are retained in their elevated. positions by means of detents 1), each ct wh ch has a hook 4 for engaging a bearing 5 contactwith a stud 21 on the adjacent str on the coacting arm 3 and has also'a pivot I detent mayswing, the said pivot being in the form of a cross-bar 6, the ends of which ex} tend into slots 7 in the slide plates. The cross-bar 6 on a cross-bar 8, the lower ends of the levers having studs 9, against which may be brought arms 10 on a rock shaft 12. At'the front edge vof each detent is a lip 18 with whichis connected one end of a spring'l l, the'other SIGN-OR TO PIKE Annmeunearne- NEW JERSEY, A CORPORATION onnnw JERSEY.

between its ends on which the is carried by levers L, swinging end connected to a stationary cross bar15'l v Coacting with each detent D is a stop A, in the form of a vertical'bar extending upward and bearing a ainst a roller or other he ring 16 and capab e of -being raised vertical yvso as to occupy a position at the rear ofthe' lower end or tail of the detent and of'being lowered below said tail, and with each stop is combined means capable of being set the part which operates the adjacent type carrier so that the stop will be raised po sition to coact with the detent whenever one of said parts is moved to set the type carrier to bring any type into printing position. While these parts may be differently constructed, I have shown each stop A as con; nected by a link 18 with an arm of a bell crank lever 19, pivoted to swing upon a cross shaft 20, the other armin position S, the strip S being-held in contact therewitli by aspring 22 connected tothe to a stationarycross'bar 23. As the stop bars A are necessarily spaced to the same extent as the different detents and hammers, and as the strips S are more widely separated, thelinkslS will diverge outwardly.

Normally, the parts prior to operation will-lie in theposition shown in Fig. 1 and the shaft 12 will rock back and forth once at each operationof the machine, and the arms 10 will be brought against the studs 9 and will vibrate the levers L, and as the s rings 14 tends to hold the upper ends of tie detents against the bearings 4, the de tents will be vibrated as the cross-bar 6 is swung by the levers L, the fulcracbein' at the upper ends of tlle detentsn This wil be the operation. in connectionwithany 'of the said arm and I above described set in. the position to bring a ty e into printing. relation with the detent ancFthe coacting hammer. When, however, one ormore of the strips S is moved so as to move the connected carrier or carriers 0 to any extent to bring any type into printing position, the stud 21 will be carried forward and the spring 22 will rock the lever 19, and the connected step A will be elevated to a position in the rear of the tail of the adjacent detent. This will result in transferring the fulcrum of the said detent from the upper to the lower end, because as the cross )ar 6 moves backward, the tail of the detent contact-in with the step A, will be arrested and will bear upon the end of the stop as a fulcrum, and the upper end will be swun" away from the bearing 5, releasing the hammer ll, which will then be thrown against the type below it and make the requisite imprint upon the paper.

As in the apparatus of the above described patent, each detent B has a wing 25 which extends laterally in position to make contact with the next detent at the right, as shown iiaFig. 2, so that if none of the type carriers at the right of the detent which has thus been operated, have been to print, the dctcnts of the said carriers will all he swung back to release the hammers to prin l. ciphers in the manner which will be readily understood and which need not be further described.

Without limiting myself to the construction and arrangement of parts shown, what I claim is:

1. The combination with the type and ham'mers of recording mechanism, of means for carrying the hammers toward the type, a detent for each hammer engaging at one end a part connected with the hammer, means for swinging said detent laterally, and

i a stop device adjustable to and from a position to obstruct the movement of the dc tent at the other end.

2. The combination with the type and hammers of a recording mechanism, of detents each engaging at the upper end a part connected with one of the hammers, and each pivoted between its ends, means for laterally reciprocating the detcnts, and a stop device for ach detent adjustable to and from a position to obstruct the lateral movement of the lower end of the detent.

3. The combination with type, carriers, operating devices, and hammers of a recording mechanism, of detents, each engaging at the upper end a part connected with one of the hammers and each pivoted between its ends, means for laterally reciprocating the detents, a stop device for each dctent adjust able to and from a position to obstruct the lateral movem nt of the detent at the lower parts where a carrier is not end, and means for shifting each stop device into obstructing position on the movement of the associated carrier to bring a type into printing position.

4.. The combination with the type carriers, operating devices and hammers of a recording mechanism, of a pivoted detent engaging each hammer, means for normally swinging said detent about its point of engagement with the hammer, and a sto 1 device adjustable to shift the fulcrum of the detent to the opposite end.

5. The combination in a recording mechanism, of hammers, a detent engaging a hearing of each hammer, means for swinging each detent laterally, and a stop device adjustable to a position to constitute a temporary fulcrum for the detent.

6. The combination in a recording mechanism, of hammers, type carriers and type,

and means for actuating the type carriers, of a detent engaging a bearing of each hammer, means for swinging each detent laterally, a stop adjustable to a position to constitute a temporary fulcrum for the detent, and means for adjusting the said stop to operative position on shitting the type carrier actuating means.

7. The combination in a recording mechanism, of hammers, detents, a cross bar to which each detent is pivoted between its ends, means for swin ing saiid cross bar, and a stop device adjusta is to a position to contact with the lower end of each detent for the purpose set forth.

8. in a recording mechanism, the combination with adjustable type carriers, operating means therefor, t *pe movable on the carriers, hammers, and detents for holding the hammers out of action, of stops, adjustable relative to the type carriers and detents, for controlling the action of the detcnts, and means controlled by the type carrier operating means for adjusting said stops.
